Definitions

  • This invention generally relates to handling and applying formed lids with flanges to cartons, and more particularly, to a method and apparatus effective for inverting flanged lids dropping from a lid forming machine, and applying the lids into full seating engagement on the cartons.
  • the cartons are usually fabricated of plastic coated paperboard erected to include four sides, a bottom panel and a hinged top cover having depending flanges overlying the upper edges of the sides.
  • a new form of carton for ice cream or the like has a removable paperboard flanged lid.
  • the carton has short vertical flanges provided along the upper edges of the sides. When folded downwardly and inwardly along the margins of the carton mouth, a peripheral sealing area is defined.
  • the separate lid covering the mouth engages the flanges and the upper edges of the sides to seal the contents.
  • the lids applied to seal the contents within the cartons are erected or formed in a lid forming machine.
  • the lids are released from the forming machine upside-down and thus must be inverted before being applied to the cartons. It has proven difficult in the past to invert the lids while maintaining the high speed operation essential to efficient production.
  • apparatus for inverting and applying flanged lids to cartons comprises upper conveyor means defining an upper feed path extending in a first direction for receiving and conveying inverted lids, inverting means for said flanged lids, to provide upright lid position during the transition from the upper feed path to a lower feed path extending in a different direction, and carton conveyor means intersecting the lower feed path at a lidding station where means are provided for applying the lids to the cartons.
  • the inverting means comprises coaxial rolls carrying permanent magnets to receive and hold metal lids received by retaining claws on the rolls, and the applying means comprises a stationary plate between the rolls to detach the lids from the magnets and press them on to the cartons.
  • the applying means comprises a stationary plate between the rolls to detach the lids from the magnets and press them on to the cartons.
  • Another object of the invention is to provide apparatus allowing full seating engagement while controlling outward bowing of the carton sides.
  • the handling and lidding apparatus of the present invention is capable of inverting formed, flanged lids into upright position to effect full seating engagement with erected cartons.
  • the apparatus in its broadest terms comprises upper conveying means defining an upper feed path extending in a first direction for receiving and conveying inverted lids; inverting means for said flanged lids to provide upright lid position during the transition from the upper to a lower feed path extending in a different direction; and carton conveyor means intersecting said lower feed path at a lidding station; and is characterised by lower conveying means defining said lower feed path moving in said second direction, said lower conveying means being positioned beneath the upper conveying means for receiving the lids from said upper conveying means, said upper and lower feed paths being spaced apart from each other; transfer means receiving and supporting the lids being discharged from the lower converying means and presenting the lids to the lidding station; and means positioned downstream of the lid transfer means for applying the lids to the cartons and comprising an endless member having a plurality
  • the method of the invention comprises the steps of directing the flanged lids along a predetermined upper feed path with the lid located in inverted position on said path; flipping the lids over into upright position on a lower feed path extending in a different direction; feeding cartons to intersect said lower feed path at a lidding station; and progressively applying the lids to the cartons at said lidding station; and is characterised by the steps of initially aligning and engaging a leading edge of each lid with the corresponding moving carton by means of a first lug on an endless member; and positively seating the lid to the carton by contacting the lid adjacent a trailing edge with a second lug on the endless member.
  • An upper belt conveyor system receives the inverted lids directly from a lid forming machine for travel in a first direction.
  • a lower conveying belt positioned beneath the upper conveyor has a receiving section positioned below the discharged end of the upper conveyor.
  • the lower receiving belt moves in the opposite direction from the upper belt and receives the lids dropping in free fall or cascading movement from the upper belt, thus forming the inverting station.
  • the upper and lower feed paths defined by the respective belts are spaced from each other to allow flipping of the flange lids to the upright position on the lower belt.
  • the lid flipping action occurs when the leading edge of the lid falls onto the lower belt and the reverse movement of the lowest belt causes the trailing edge to continue forwardly, and thus flip over.
  • the lid lands on the lower belt in the upright position in readiness for applying to the cartons.
  • a vertical guide plate is positioned adjacent the upstream end of the receiving section of the lower conveying belt and is operative to deflect the trailing lid edge to prevent overflipping and to thus guide the lid into the desired upright position.
  • the upright lids are conveyed along the lower feed path for discharge onto a transfer plate extending downwardly from the discharge end of the lower conveyor belt and in the direction of lid travel, allowing the lid to slide into the operative position for engagement with the carton arriving at the lidding station on a carton conveyor.
  • the leading edge of the lid positioned at the lidding station abuts one of a plurality of lugs attached to an endless idler belt.
  • the lug holds the lid stationary and in alignment with an advancing carton on the carton conveyor intersecting the lower feed path adjacent the transfer plate.
  • Contact between the leading lid edge and moving carton drives the lug forward while pulling the idler belt around supporting idler rollers.
  • One of the idler rollers may be braked by adjustable brake means to provide the desired accurate positioning of the lugs and firm engagement for improved control of the lidding operation.
  • the carton moves beneath the idler belt, the belt is pushed forward and the lid is restrained and progressively seated on the carton.
  • the progressive engagement of the lid in conjunction with the control provided by the seating lugs and the side guide rails results in a gentle and smooth lidding operation. This action effectively prevents outward bowing of the carton walls.
  • a second or trailing lug on the idler belt progressively presses down adjacent to the trailing edge for full lid seating engagement. The trailing lug is then positioned at the lidding station to intercept the next lid as the previous lug disengages from the carton, and the belt stops.
  • a pair of seating rollers coaxially mounted on opposite ends of the downstream idler roller is dimensioned to contact the lateral edges of the lid on the carton to assure full seating engagement.
  • a lid handling apparatus 10 constructed in accordance with the present invention to invert and apply flanged lids F to carton K is illustrated.
  • the lids F are initially received from a lid forming machine (not shown) through an enclosed guide 11.
  • the lids F drop in an upside down position onto the upper conveyor, generally designated by reference indicia C i .
  • the upper conveyor C comprises belt means defined in the preferred embodiment by spaced endless belts 12 (see Figure 2).
  • the conveyor C is inclined upwardly from the guide 11 and a drive roller 15 at the discharge end.
  • An intermediate guide roller 16 is positioned along the lower run of the belts 12.
  • the roller 15 is driven by suitable drive means 17 in the direction of the feed arrow A shown in Figure 1.
  • the flanged lids F moving along the upper run of conveyor C, defined the upper feed path of the handling apparatus 10 of the present invention.
  • a lower conveyor C 2 Positioned below the upper conveyor C 1 is a lower conveyor C 2 having belts 20 driven by driver roller 21, receiving input driving force from drive means 17, and idler roller 22.
  • the conveyor C 2 is inclined downwardly so that the flanged lids F are abutting and slanted downwardly toward a lidding station L.
  • the belts 20 are of an over-running type providing constant forward feeding force to the abutting lids F (see feed arrow A,).
  • the lower feed path is of course defined as the path of movement of the lids F, along the lower conveyor, as shown in Figure 1.
  • the inverting station of the handling apparatus 10 - is designated by the reference indicia I. As best shown in Figure 1, the inverting station I is adjacent the discharge end 13 of the upper conveyor C i . The bottom of the inverting station I is formed by a receiving section 25 of the lower conveyor C 2 .
  • the flanged lids F free-fall or drop in a cascading manner over the end of the conveyor C l .
  • the leading edge of the lid being inverted assumes the dotted line position, as shown by the lid F,.
  • the leading edge of the lid F is directed in a downward direction and assumes a new position as lid F 1 (also shown in dotted line outline in Figure 1).
  • the lid flips over into the position shown by the lid F 2 , with the trailing edge moving as shown by the arrow B.
  • This movement is in the same direction as the feed path movement in accordance with the arrow A along the upper conveyor C 1
  • the trailing edge of the lid F 2 engages a vertical guide plate 26 with the leading edge continuing along with the lower conveyor C 2 into abutting relationship with the next-in-line lid F.
  • the guide plate 26 controls the flipping action of the lid F 2 and prevents over flipping that could provide jamming.
  • the spacing between the discharge end 13 and the guide plate 26 is less than the length of the lids F to assure this action.
  • the lids are handled in a controlled manner during the transition.
  • the flipping action is rapid to maintain the high speed operation.
  • the reverse movement of the conveyor C 2 also assures proper inversion of each lid F to the desired right-side-up position.
  • All of the lids F along the lower conveyor C 2 are in abutting relationship so that the lids are maintained in readiness along the feed path.
  • Adjacent the discharge end of lower conveyor C 2 is a transfer plate 30 supporting the flanged lid F 3 at the lidding station, as well as the next-in-line lid F 4 .
  • the top of the lid F 3 is engaged from above the lower run of the belts 12 at the turning point of the intermediate guide roller 16.
  • the lower portion of the handling apparatus 10 of the present invention includes a feed conveyor C 3 for the cartons K moving along the feed path A 2 .
  • the feed path A 2 intersects the feed path A 1 of the flanged lids at the lidding station L (note flanged lid F 3 positioned in readiness for seating on carton K i ).
  • the cartons K are driven serially by suitable chain conveyor means having driving lugs 35.
  • Guide rails 36, 37 (see Figures 1 and 2) engage the sides of the cartons, and in addition to guiding the cartons along the feed path A 2 , help prevent outward bowing of the sides during the lidding operation.
  • the lid F 3 in Figure 1 is being driven forwardly by the lower run of the upper belts 12 around guide roller 16, and by the pushing action of the next-in-line lid F 4 .
  • the carton K 1 being fed by the carton conveyor C 3 moves under the lid F 3 and between the depending flanges.
  • the lid applying apparatus generally designated by the reference 40, includes an idler belt 41 having a plurality of lugs 42, 43, 44.
  • the belt 41 is mounted for idler movement by rollers 45, 46.
  • Attached to the support shaft for the roller 46 is an adjustable brake means 47 (see Figure 2).
  • Positioned at the sides of the belt 41 are two seating rollers 50, 51.
  • the rollers 50, 51 are larger in diameter than the roller 46 supporting the belt 41, and accordingly are operative to engage the lateral edges of the flanged lid to assure final seating action.
  • the cartons K are being transported along the conveyor C 3 and the lid F 3 is stopped in engagement with the seating lug 43 positioned at the lidding station L.
  • the lug 43 is pressed down on to the rear edge of the preceding lid F s of the preceding carton K 2 to firmly seat the rear of that lid.
  • the seating lug 44 is relatively wide providing a firm abutment for the leading edge of a lid to engage.
  • the seating lug 42, the seating rollers 50, 51 and the trailing lug 43 all firmly engage the lid F 5 on carton K 2 to provide the seating function.
  • the lateral edges of the lid are firmly pressed down providing the final seating function.
  • the lids F are fed along an upper feed path and to an inverting station I.
  • the lids cascade down to a receiving section 25 of the lower conveyor C 2 and defining the lower feed path.
  • the lower conveyor C 2 is moving in the opposite direction, and thus moves the leading edge of the lid F causing the lid to flip and assume the desired upright position.
  • a vertical plate 26 confines the lids and assures the proper flipping action.
  • the lids are then fed to the lidding station L for interception by the cartons K.
  • the lid applying apparatus 40 gently applies the lids while maintaining control of the lids along the feed path.
